DOUBLE-U1? UMBRELLA.

Specification of Letters Patent.

Application filed February 11, 1914. Serial No. 817,981.

To (ZZZ whom it may concern Be it known that we, CARL J. FRISK and EMIL Onuuennu, a citizen of the United States and a subject ofthe King of Sweden, respectively, residingat San Francisco, in the county of San Francisco and State of California, have invented new and useful Improvements in Double-Up Umbrellas, of which the following is a specification.

The object of the present invention is to provide an umbrella which can be quickly and conveniently reduced in length so as to enable it to be inserted in a valise, traveling bag, or other receptacle of comparatively small length, for the purpose of traveling or storage, and which can also be quickly and conveniently extended for use.

In the accompanying "drawing, Figure 1 is a broken sectional view of the umbrella open, the stick being shown in side elevation and many of the ribs being omitted for the sake of clearness; Fig. 2 1s a slmilarf view of the upper portion of the umbrella folded into a small compass; Fig. 3 is a sectional view; on an enlarged scale of the middle portion of the stick; Fig.4 is an enlarged longitudinal sectional view ofa latching device; Fig. 5 is a cross-sectional view of the same; Fig. 6 is an enlarged side view of a rib pivot; Fig. 7 is a plan view of the same. I

Referring to the drawing, 1 indicates the stick of the umbrella, which is inthe form of a metal tube made of separable sections 2, 3 and 4. The middle section 3 is formed with reduced tubular ends, which fit snugly within the adjacentends of the sections 2 and 4, and in order to connect said sections with each other there is pivoted at 6 in the section 3, a spring 7 havinga humped portion 8 extending through a narrow longitudinal slot 9 in the section 3 and adapted to be repressed bythe thumb to operate the spring. Said spring has its ends bent outwardly to form catches 11 and 12, extending through holes in the reduced terminal.

portions of the middle section 3, and adapted to extend through holes 13, 14,correspondingly located in theadjacent ends of the tube sections 2 and 4. Said catches 11, 12,. are shaped to provide beveled outer surfaces, as shown at 16, 17, so that when the ends of the section 3 are properly inserted in. those of the sections 2 and 4 they look automatically. By pressing in the humped portion of the spring said catches can be tween which are received the collapsed sides of terminal portions of tubes 23, surrounding the adjacent ends of outer rib sections 24. The forked outer end of each tube 21 is contained between the forked outer end of a stay 26, and through small registering holes in the outer ends of the stay 26 and the tubes 23 and E21 passes a pivot pin 27, by which means both the rib sections 19, 24 are pivctally secured to the stay 26 and to each other. The inner ends of these stays 26 are pivotally attached in the usual manner toa slidle ring 28 slidable upon the umbrella stic c. i

Around the outer rib sections, and attached thereto at a short distance from their pivotal attachments to theinner rib sections,

are secured tubes 29 having inward extenw sions which pass between, and are pivotally sccured,fas shown at 31, to forks 32 secured the usual manner toa runner 34, slidable upon the stick independently of the slide ring 28. Secured to said runner 34 is a tube 36, having therein alongitudinal slot 37 adapted toregister, in the closedposition of theumbrella, with a slot 38 in the stick, and in the open} position with a slot 39 therein. Through said slot 37a catch 41 extends inwardly from a sleeve 42 surroundingthe tube 36 and contained between a shoulder43 on said tube 36 and a tube 44 around the tube 36, said tube 44 being pressed downwardly by alcoiled spring 46 compressed between the tube 44 and a shoulder 47 on the tube 36. The tube 44 has a downwardly extending sloping or wedge Patented Nov. 17, 1914.

compressing the coiled spring 46. l/Vhen pressureis released from the sleeve 42, the force of the compressed springcauses'the sloping portion of the tube 44 toabut against the sloping portion of the sleeve 42 and restores said sleeve 42 to its normal'position, in which the catch 41 extends inwardly through the slot 37' and" through the slot 39 or 38, as the case may be,

thus holding it ineith'er the open or closed,

position as desired. A tubular casing 52 surrounds the tube 36 and has "a" heie on one side 'into' which the extended side of the sleeve 42 fits snugly vand closes it. The cover 50 of theumbrella" is attachedto the when. said slide ring 28 is arrested thereloyi The runner 34; can,.;however,,-be still pushed upwardly, until comes substantially in contact with the slide ring 28, in which po sition the inwardly extending catch 41 springs inwardly'into-theupper slot 39." By

the {final upwardmovement ofthe runner 34into contact withthe slide ring 28 the rib sections are straightened; out as v much as is permitted by thereover 50 of the umbrella; To close the umbrella; the thumb is applied tofthe extended portion 51 'of the sleeve to withdraw the catch 41 from the slot 39, and the tube withdrawn in the; usual manner, the catch 11 entering, the lower slot 38to-hold it inits closed position.

To bring the umbrella to-a' compact form.

suitable for packing for transportation or storage; the outer ends of the outer ribseek tions are encireled by" the and at the same time pressure is applied to thesleeve 42th release the tube 36, and said tube and the; runner are pushed upwardly. By reason of the-outer rib sections being helddown inl the position-in which they are almost parallel with the stret chers 3'3,,.the, runner 34 moves alongthe'stickgat a much' greater distance from the slide rin'gI'QS than when opening the umbrella} for use as be" fore explained. Consequently{ when the slidering 28 arrives at. the upper'icatch 12;;

the runner34 has also arrivedat the-humped portion 0 f; the spring, as-shown ingdotted lines,- and has repressed the same Within the tube section This movement of] the spring caused by; the movement of the} humped portion into the tube section" 3',

also

causes the catch 12 to be withdrawn, but not far enough to disconnect the tube sections, sothat'the slide ring'28 passes said catch 12 and oanmove into close proximity with the fixed ring 18. The upper portion of the runner 34 is formed in its inner side with a recess or cup 54 which can receiveth'e upper catch 12 whenit arrives thereat. In this position all the inner and outer rib sections and stays and stretchers are collapsed very closely around :theupper tube section. The tube'sections can" now be detached from each other by pressing inwardly the hump shaped portion of the spring; and; drawingi the outer tube sections 2," 4" from themiddle tube section3. Thje'tube' sections 3 and 2, the latter supporting at itsbuterend the usual handle 55', arem'ade of substantially the same" length as the combined length" of the upper'stay section and the"ribsection when in'the" closed position just described, so that the totallength 'ofan umbrella'of orclina1 ysize,w\vl1en it is taken to pieces, need not be more than about fourteen inches, and can thus be packed'or st'or'ed in'a comparatively small compass andmayfbe' carried in' the coat pocket with ut itsldeing 'to'o conspiciiou'sl I There are many important advantages ssesseu'by; a' foldablefumbrella' of the above described construction. First, by're'a' son oftlie umbrella" ribs folding'inw'ard, the umbrella can be fblded all at once; whereas with foldableumbrell s in' which the ribs" foldoutward; muchtime is occupied ina'r ra'nginglithe cover around-merits, fact it" is extremely difficult windy weather to fbldi the umbrella at} all; This capability" of the ribs folding inwardly is produced by our improved method o'f'usin'g stays and stret'oh'ershand pivoting the" two sections of the ribs together, It'i will be observed that the pivot of' each" isslightly about'[one'-sixteenth of'an inch; he neath or within theinner edges ofthe ribs." In reducing theumbrella to a compactform forthe purpose oftransportation or other" wise, the ribs and cover automatically as sume' their proper positions by the mere pushing upward of the tube '36, andall that" is necessary'is to detach (the stick section'sfrom" each other,. which is easily done, requiring only the pressure of the th'umliupon? the humped portion of the spring "and-the draw ing out of the terminal sections fronrthe' middle section;v I Such operation evidentlyrequires no skill v or experience to perform. Furthermore, theoonstr'uction is such that when the ribsectio'ns arefolded'on one another the cover of the umbrella is-folde'd so? as th fit very snugly and tightly around said ribs, and leave no loose parts whichjhjave is due to the cov'e'r i being on the" outside of the ribs when folded-together," and to the" to be separately arranged'in position This" positions of the pivots, which cause the rib sections to fold on one another at exactly the right point to cause the cover to fit tightly, yet not too tightly thereover. A further advantage is that both the inner and outer rib sections are each attached at two points to rigid material, the inner rib sections to the fixed ring and to the stays and the outer ribsections to both the stays and stretchers. Consequently both rib sections are under full control and do not require to be operated by hand in order to change the condition of the umbrella.

We claim 1. An umbrella having a tubular stick, inner and outer. rib sections, stays pivoted to the inner rib sections, stretchers pivoted to the outer rib sections, a slide ring pivoted to the stays, a runner pivoted to the stretchers, a spring having a catch projectingthrough a hole in the tubular stick, and having a protuberance extending through a slot in the tubular stick, the

lengths and arrangement of said rib sections, stays and stretchers being such that, in the upward movement of the runner to open the umbrella, the runner engages said protuberance to withdraw the catch when the slide ring arrives thereat to permit said slide ring to pass thereover.

2. An umbrella having a tubular stick, inner and outer rib sections, stays pivoted to the inner sections, stretcher-s pivoted to the outer sections, a slide ring pivoted to the stays, a runner pivoted to the stretchers, means projecting through an upper hole in the tubular stick for arresting the slide ring in its upward movement, and means projecting through a lower hole in the stick and operatively connected with the firstnamed means to withdraw the latter with the withdrawal of the former, the outer rib sections being secured to the stretchers at a distance from the pivots of the rib sections.

In testimony whereof we have hereunto set our hands in the presence of two subscribing witnesses.
